DETAILED DESCRIPTIONS OF THE PREFERRED EMBODIMENTS

Referring now to the drawings in detail, reference is first made to FIG.1, wherein a panel generally designated 10 of this invention isillustrated. The panel 10 includes a base layer 11 of a molded syntheticpolymeric building material that is adapted to be weather-protected inthe installed condition on a building structure, and a layer 12 ofasphalt based building material.

The layer 11, of polymeric material may be comprised of thethermoplastic material disclosed in U.S. Pat. Nos. 6,808,785; 7,351,462;7,141,200; 7,141,201, as representative of polymeric materials.

The layer 12 of asphalt based building material may be constructed inaccordance with the detailed description of FIG. 6 hereof, for example,or of laminates of materials of the type of FIG. 6, or a material of thetype described with reference to FIG. 6 having an additional overlay ofadhesive and granules applied to a surface thereof, as representativeconstructions for the layer 12 of asphalt based building materials.

The polymeric 11 layer of building material may be provided withcut-outs or voids, recesses or the like 13, such as are illustrated inFIGS. 2 and 3, outlined by peripheral ribs 14, 15, 16 and 17, andsupported by interior ribs 18, 20, 22 and 23, for providing rigidity tothe panel 10, as well as support, so that, for example, in the eventthat a panel 10 is installed on a roof or the like, installers will beable to safely walk on an exterior surface 24 thereof, withoutcollapsing the panel 10.

The asphalt based building material 12 may be comprised of upper andlower courses 25 and 26 of individual shingles or tiles or portionsthereof, with adjacent such individual tabs of shingles or tiles beingseparated by actual or simulated slots 28 that are generally verticaland spaced apart from each other, to give the overall appearance of aplurality of courses of individual tabs of shingles or tiles 27. In thecase of actual slots, the upper surface 30 of the polymeric layer 11will be exposed and visible through the slots 28. Such exposed portionsof the polymeric layer 11 are appropriately stabilized to theenvironment. In the case of simulated slots, defined by generallyvertical lines appearing on the upper surface 24 of the asphalt basedlayer 12 and on a lower edge of the asphalt based layer 12 as shown inFIG. 2, the lines 28, 32 that define the simulated slots will appearonly as aesthetic markings.

As shown in FIG. 1, the right-most edge 33 of the asphalt based layer 12overlies the right-most edge 34 of the layer of polymeric buildingmaterial and the lowermost edge 35 of the asphalt based buildingmaterial layer 12 protrudes below the lowermost edge 36 of the layer ofpolymeric building material, so that the right edge of the panel 10 asillustrated in FIG. 1 can be in lapped relation with a left-most edge ofa next adjacent, substantially identical panel to that 10 of FIG. 1,which adjacent panel is not shown in the illustration of FIG. 1.Similarly, when the panel 10 of FIG. 1 has its lower edge disposedagainst a next-subjacent panel (not shown), the overlying edge 35 of theasphalt based panel 12 will overly a portion of a layer of polymericbuilding material of a next-subjacent panel that is similarlyconstructed to the construction of the panel 10 of FIG. 1.

Thus, the left-most edge 37 of the layer of polymeric building material11 protrudes beyond the left-most edge 38 of the asphalt based layer 12of material, and the upper edge 40 of the layer of polymeric buildingmaterial 11, likewise protrudes above the uppermost 41 of the layer 12of asphalt based building material, as illustrated in FIG. 1.

It will thus be seen that when panels of the type 10 of FIG. 1 areapplied to a surface of a building structure (not shown), next laterallyadjacent panels will be in lapped relation to each other, as will bevertically adjacent such panels 10 be in lapped relation to each other.

One or more photovoltaic panel portions 42 may optionally be provided onselected tabs of the upper surface 24 of the asphalt based layer 12 ofbuilding material, for capturing photovoltaic energy when the panel 10is installed on an exterior surface of a building structure, and thephotovoltaic panel portions 42 may be provided with wires 43, passingthrough holes 44 in the panel layers 11, 12, for transmittingphotovoltaic energy through panels 10, as illustrated in FIG. 3.

With reference to FIG. 3A, it will be seen that a pair of panels 10 and10′ are shown, with the panel 10′ being subjacent to the panel 10, inlapped relation as described above, and wherein wires 43 and 43′ forforming the electrical connections between photovoltaic panel portions42 and 42′ for the panels 10 and 10′, are connected to each other,passing through the layers 11 and 12 and 11′, 12′ of respective panels10 and 10′ at 44 and 44′, respectively.

Wire connection devices are provided, for connecting wires 43 and 43′ ofvarious panels such as 10 and 10′ to each other, from panel-to-panel viaconnectors 45, in the form of male and female connector elements 46, 47,respectively, for connecting together wires such as those 43, 43′ of apair of panels such as 10, 10′ to each other, as shown in FIG. 3B.

At the upper left corner of the illustration of FIG. 1, there isprovided a temperature sensor 50, more clearly shown in the detailillustration of FIG. 1A, which temperature sensor 50 is subject toexpansion and contraction as a function of temperature, as is the panel,and which sensor provides a visual indication thereon, in the form ofthe gradations 51 of thermal expansion and contraction characteristicsof the panel 10, at a given ambient temperature of the panel 10. Forexample, the temperature sensor 50 may be constructed in accordance withthe disclosure of U.S. Pat. No. 6,939,036, the complete disclosure ofwhich is herein incorporated by reference.

With reference to FIG. 5, similar components and portions of componentsto those illustrated in FIG. 4 are identified by the numbers 51′, 52′,53′, 54′, 55′, 56′, 57′, 58′, 59′, 60′, 61′, 62′, 63′ and 64′, exceptthat the lips 61′ and 62′ are in underlying relation to lowermostrespective edges 63′ and 64′ of the asphalt based shingle or tile layers53′, 54′ seating the shingles or tiles 53′, 54′ against the flatportions 56′, 57′ of the synthetic polymeric based building material52′.

The lips 61, 62 and 61′, 62′ can be eliminated to yield a shingleappearance and structure like that addressed hereinafter for the shingleof FIG. 29.

Referring now to FIG. 6, there is illustrated a transverse sectionalview, taken through a layer of asphalt based building material 70 inaccordance with this invention. The material 70 is comprised of a layerof mat 71, which can either be of organic or inorganic construction, butwhich will preferably be of inorganic construction, generally comprisedof a cross-weave of fiberglass strands 72, 73, impregnated with abituminous material, such as asphalt 74, having an adhesive 75 on anupper surface thereof, which adhesive may also be an asphaltic based(bituminous) adhesive and may or may not comprise the same adhesivematerial that is the asphaltic material 74, and with a layer of granules76 on an upper surface thereof, adhered thereto, by the adhesive 75. Anadhesive 79 will generally be provided on a lower surface of the mat 71,which adhesive 79 may or may not be the same as the asphalt basedadhesive 74. The adhesive 79 will be provided with a layer of fineparticles 77 on a lower surface thereof as shown at FIG. 6, which fineparticles may be of sand or mica construction or of any other suitablematerial, which layer of particles 77 will generally be comprised ofsmaller particles than the granules 76 that appear on the upper surfaceof the asphalt based building material 70.

With reference to FIG. 7, a pair of adjacent panels 80, 80′ of thisinvention are provided, each of which has a base layer 81 or 81′ ofsynthetic polymeric building material and an overlying layer 82 or 82′of asphalt based building material, constructed similarly to thatillustrated in FIG. 3A, for example, but wherein adjacent edges 83, 83′of the base layers 81, 81′, are lapped in interlocked relation with eachother, as shown, and with an edge portion 84 of the asphalt based layer82 of building material, overlapping a portion 84′ of the layer 81′ ofpolymeric based building material. It will be understood that thelapping and interlocking relationship shown in FIG. 7 and as describedabove can take place between right and left laterally adjacent panels inaccordance with this invention, or between vertically adjacent panels inaccordance with this invention, or both.

Beneath the synthetic polymericbuilding material layer 102 there is provided a layer 108 of insulationmaterial, preferably a foam type insulation, although the same could bea fiberglass based insulation or made of other insulating materials. Theleft end 110 of the panel 100 would normally be the end that is thelowermost, generally horizontal edge of the panel 100 when the panel isinstalled on a building structure. In order to cover the left edge ofthe insulation layer 108, the left-most end 111 of the polymeric layer102 covers the edge 112 of the insulation layer, so that the insulationlayer's lower edge 112 is not visible from below, when the panel 100 isinstalled on a building structure, with the end 110 being the lowervertical edge thereof.
